The real answer is a DCP with a compatible player. It's how films are delivered to cinemas. It's an MXF file, which itself is a series of JPEG2000 frames, plus a multitrack WAV file.

Barring that, PlaybackPro is widely used in the corporate even world. 90% of the time I see MacBook Pros used, mainly because it's a Mac only program. Once I saw an iMac, but that's overkill in my opinion.
